So, it sounds like you need to just do "CYGWIN=nontsec tar x ..." followed by "attrib +R c:\path /s". nontsec prevents Cygwin from setting the ACLs and attrib sets the read-only bit. > file permissions.

No need to invent anything here either, that program has existed since the dawn of MSDOS era as 'attrib'.
